Product description

The DT4227 UI … Process indicator is used to display the signal of measuring transducers with 0-20 mA / 4-20 mA / 0-10 V / 2-10 V / 0-5 V output in physical measurement units. Any display range can be assigned to the input signal range.
The DT4227 UI has a 5-digit, 57 mm character height LED display that can be read easily from a distance of up to 30 m, the brightness of the display can be adjusted.

A 20 VDC supply voltage is available at the input to power a passive 4-20 mA transmitter.
The device has dual limit relay outputs (SPST), which are freely programmable, and several limit modes can be selected.
The front panel push buttons allow you to set the operating parameters via a simple menu system or via a USB interface with a single-screen (free) setup program: input signal range selection, input signal averaging, scaling, display frequency, display brightness, limit values, limit value modes, etc.
The device is available with two power supply options:

  • DT4227 UI type 24 VDC ± 10%,
  • DT4227 UI PS type 230 V AC/DC ± 10%.
